Personally, I feel that they were well within their rights, they can’t let go until the perp has either given up or they have him pinned down in such a way that a hand is free to cuff him.
NOTE: Vlad says: “I think the police should drop this rapist-suspect off at the house of the people objecting to the manner of the arrest. That would solve so many problems at once.”
Honestly folks, who would want to be a policeman in an ultra politically correct place like Norway?
As for the anonymous witnesses recording the scene on a cell phone, I wonder whether their attitude would have been different had it been their daughter?
They would not be talking about brutality in that case – guaranteed.
In Singapore rapists get the birch on their backs – not much of such behavior there.
